The TA-53M was developed for radio amateurs looking for a 3 element 5 band beam with smallest size.
The development criteria were:

• One feedline only
• A very wide band antenna which works nicely on solid state amplifiers.
• An antenna as smal las possible for 5 bands.
• Desined for optimum gain on 5 bands, on a 4.3m boom.
• Minimal influences within the antenna due to the narrow spaced elements.
• An antenna which withstands severe weather conditions.

We think that we made it. One has to accept the small drawback of a less favorable fron/back ratio, this is given with just one director and one reflector.

This is the antenna for the demanding amateur who is looking for an all purpose antenna. The TA-53M is equal or better to other 3 element beams with 4.3m boom, better in relation to gainm bandwidth, SWR and construction.

Although we call the TA-53M light and small, it is heavier than the Mosley TA-33M and up to twice as heavy as some competitors products. The reason for this is the very solid construction. At first the TA-53M was designed as a lightweight antenna for military and commercial applications...
The TA-53M can be extended to 30 and 40m. The extension kit for 40m is the TA-40KR, that for 30m the TA-30KR.
